Process for winding tyre surface and system thereof

Abstract

The invention provides a tire tread winding method and a system thereof. The method comprises the steps as follows: a rubber sheet is extruded from an extruding machine, and then is cooled by a rubber-sheet cooling roll; a plastic film is stuck to the rubber sheet through a laminating mechanism at the same time; the film rubber-sheet is rolled up by a winding mechanism, and then is turned over or preserved; the film rubber-sheet roll is unreeled by adopting a center unreeling machine; then the plastic film and the rubber sheet are separated through a film and rubber-sheet detaching mechanism, and the plastic film is collected; the rubber sheet is delivered to a twister for tread winding. The system thereof comprises a first working-procedure device and a second working-procedure device; according to the production and the transportation direction of the rubber sheet, the first working-procedure device comprises the extruding machine, the rubber-sheet cooling roll as well as the laminating mechanism, and the winding mechanism in accordance with the installation positions; the second working-procedure device comprises the center unreeling machine, the film and rubber-sheet detaching mechanism, and the tread twister in accordance with the installation positions. The tire tread winding method and the system thereof increase the utility ratio of the extruding machine, the quality of the rubber sheet, and the winding quality.

Description

technical field [0001] The invention relates to the technical field of tires, in particular to a tire tread winding method and system thereof. Background technique [0002] In the production process of tires (especially engineering tires), tread winding production is the last production process in the tire molding production process, and it must wait for other molding production processes to be completed, so tread winding production is not a continuous process. Production. The extruder is the equipment that supplies the rubber film for winding in the tread winding equipment. The general method is that the film extruded by the extruder is cooled and then directly supplied to the winding machine for winding production. In this way, when a tire is wound, the extruded The machine must stop and wait for the winding process of the next set of tires. However, the extruder can extrude films with stable and consistent quality only during continuous production, which causes large fl...

AI Technical Summary

Problems solved by technology

However, the extruder can extrude films with stable and consistent quality only during continuous production, which causes large fluctuations in the quality of the extruded films, which directly affects the quality of the tread.

[0003] In the process of winding production, the film extruded by the extruder is in a soft and highly elastic state, and it needs to go through many conveying links before reaching the winding machine, during which the film will be stretched, and the cross-sectional shape of the film will change after stretching , and this change is irregular, resulting in errors in the dimensional accuracy of the winding tread
